HARROW.

SPECIFICATION forming part of Letters Patent No."3%7,10G, dated August 10, 1886.

\ Application filed March 18, 1886. Serial No. 195,767. (No model.)

To all whomit may concern:

Be it known that I, JOsEPH HILDESHEIM, of Alton, in the county of Sioux and State of Iowa, have invented a new and useful Improvementin I-Iarrows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved harrow. Fig. 2 is asectional rear elevation of the same, taken through the line as 00, Fig. 1. Fig. 3 is a sectional side elevation of a part of the same. Fig. 4 is a front elevation of the part of one of the tooth-bars, and showing a tooth attached thereto. Fig. 5 is a side elevation of one of the barrow-teeth. Fig. 6 is asectional elevation of one of the angleirons for holding the teeth.

The object of this invention is to provide harrows constructed in such a manner that they will readily adjust themselves to the surface of uneven ground, and can be readily adjusted to serve as pulverizing-harrows or as smoothing-barrows.

The invention consists in the construction and combination of various parts of the harrow, as will be hereinafter fully described.

The harrow is made in two sections, each of which is formed of two longitudinal bars, A, and five (more or less) tooth bars, B. The tooth-bars B are passed through slotted holes in the longitudinal. bars A, and are secured in place by clamps G, set-screws, or other suitable means. The clamps O are made in the form of plates, forked at their lower ends to receive and fit upon the tooth-bars B, and have yokes bolted to their lower ends at the lower sides of the said tooth bars. The clamps C are pivoted to the sides of the longitudinal bars A by bolts or screws passing through the upper ends of the clamps, and through or into the said longitudinal bars A, in such positions that the barrow-teeth will be in a vertical position'when the tooth-bars B are at one end of the slotted holes in the bars A, as shown at the left-hand part of Fig. 3, and will be in an inclined position when the said tooth-bars are at the other ends of the said slotted holes, as shown at the middle part of Fig. 3, so that the implement will be a pulverizing-harrow when the draft is applied to one end, and a smoothing-barrow when the draft is applied to the other end, the toothbars B being moved from one end of the slotted holes in the longitudinal bars A by the resistance of the soil to the teeth. The longi tudinal bars A are strengthened in position by diagonal braces D, the forward ends of 63 which are attached to the forward parts of the said bars A. The brace-bars I) cross each other at the centers of the sections, and their rear ends are attached to the rear parts of the longitudinal bars A, as shown in Fig. 1.

E are the harrow-teeth, the upper parts" of which are bent over at right angles, and have screw-threads formed upon'their ends.

F are angle-irons, which have holes in their ends, as shown in Fig. 6. 0

In securing the harrow-tecth E to the toothbars B, the angle-irons F are placed upon a lower angle of the tooth-bars B, with one end projecting above the said bars and the other ends at the sides of the bars. The teeth E are inserted in the holes in the lower arms of the angle-irons F and pushed downward,and their upper ends are inserted in the holes in the upper arms of the said angle-irons,and have nuts G screwed upon them, as shown in Fig. 3.

To the centers of the central toothbars of the barrow-sections are pivoted the ends of an arched bar, H, to connect the said sections and keep them in proper relative positions, while allowing them to adjust themselves freely to the surface of the ground. In the center of the arched bar II is formed aperforation,into which is hooked the rear end of a 'rod, I, the forward end of which is hooked into a perforation in the center of the draft-bar J, or into a staple or clevis attached to the said draftbar. The rod I is made of such a length as to hold the arched bar 1 1 in a vertical position when the harrow is in use.

To the centers of the inner sides of the longitudinal bars A are attached eyebolts or staples K, to which are attached the rear ends of the draft-chains L. The draftchains L are passed through eye-plates or staples M, attached to'thc forward tooth-bar B, upon the opposite sides of and at a little distance from the centers of the said iootlrbars. The forward ends of the draft-chains L are attached to staples or clevises N, attached to the draftbar J at points about midway between thelongitudinal lines passing through the eye-plates M and the longitudinal bars A. This arrange ment of the draft chains produces what is known as a vibrating harrow that is, one in which the sections are so attached to the draft-bar that one section can move ahead of the other straight with the line of draft should either of the said sections strike an obstruction or run in deeperon uneven ground, thereby lessening the danger of breakage.

Vhen it is desired to have a non-vibrating harrow,the draft-chains L are passed through staples O,attached to the ends of the longitudinal bars A, and are attached at their forward ends to staples or clevises P, secured to the draft-bar J at points about in line with the said longitudinal bars A.

To the draft-bar J, at points about midway between its center and ends, are attached the ends of a bail, Q, in the center of which is formed an eye, R, to receive the draft attachment.

The harrow-sectionsare provided with a set of staples, M O,at both ends, so that the draft can be readily applied to either end to form a pulverizing-harrow or a smoothing-barrow, as may be required.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a harrow, the combination, with the barrow-sections A B A B and the draft-bar J, of the arched bar H,pivoted to the centers of the said sections,and the connecting-rods I, attached to the said arched bar and to the draft-bar, substantially as herein shown and described, whereby the said sections will be held securely in their proper relative positions, while being free to adjust themselves to the surface of the ground, as set forth.

2. In a harrow, the combination, with the harrowseetions A B A B, having staples K, and two sets of staples, M and O,and the draftbar J,having two sets of staples,N and P,of the draft-chains L, substantially as herein shown and described, whereby the harrow can be readily adjusted as a vibrating harrow or as a non-vibrating harrow, as set forth.

3. In a barrow, the combination, with the tooth-bar B, of the teeth E,having theirupper parts bent at right angles, and having screwthreads on their upper ends, the angle-irons F, perforated at their ends to receive the said teeth E, and the nuts G,screwed upon the upper ends of the said teeth, substantially as herein shown and described,whereby the said teeth are readily and firm] y secured to the said tooth-bars, as set forth.
